WinOptimizerContextHandler64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like WinOptimizerContextHandler64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Ashampoo WinOptimizer) could share the same WinOptimizerContextHandler64.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when WinOptimizerContextHandler64.dll is attempted to be loaded either when Ashampoo WinOptimizer is starting up, or in some cases already running. Some of the most common WinOptimizerContextHandler64.dll errors include:
- Access Violation at address - WinOptimizerContextHandler64.dll.
- WinOptimizerContextHandler64.dll could not be found.
- Cannot find C:\Program Files (x86)\Ashampoo\Ashampoo WinOptimizer 2020\WinOptimizerContextHandler64.dll.
- Cannot register WinOptimizerContextHandler64.dll.
- Cannot start Ashampoo WinOptimizer. A required component is missing: WinOptimizerContextHandler64.dll. Please install Ashampoo WinOptimizer again.
- Failed to load WinOptimizerContextHandler64.dll.
- The application has failed to start because WinOptimizerContextHandler64.dll was not found.
- The file WinOptimizerContextHandler64.dll is missing or corrupt.
- This application failed to start because WinOptimizerContextHandler64.dll was not found. Re-installing the application may fix this problem.
Your WinOptimizerContextHandler64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Ashampoo WinOptimizer), or deleted by a malware infection. Furthermore, WinOptimizerContextHandler64.dll file corruption could be caused from a power outage when loading Ashampoo WinOptimizer, system crash while loading WinOptimizerContextHandler64.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
